GitHub adds repo-level Dependabot runner config

GitHub Changelog·September 29, 2026·high confidence

Why it matters

  • →Enables isolated execution of security scans in specialized self-hosted environments.
  • →Allows granular control over compute resources for dependency updates at the repo level.
  • →Reduces risk of credential leakage by keeping scanning jobs off shared default runners.
GitHub adds repo-level Dependabot runner config
©GitHub Changelog

GitHub has introduced repository-level configuration options for Dependabot runners, allowing administrators to specify runner types, custom labels, and runner groups for version and security updates. This feature extends existing organization-level controls, enabling teams to direct Dependabot jobs to self-hosted runners with access to private package registries or specialized environments. The setting is available for private and internal repositories on github.com but remains hidden for public repositories and GitHub Enterprise Server. Security configurations do not currently enforce these runner settings.

GitHub external custom properties public preview

GitHub finally bridges the gap between code and corporate governance with external custom properties. By allowing systems like CMDBs to push read-only metadata—ownership, compliance status, service tiers—directly into repos, it stops developers from manually tagging repositories in silos. The real win is the dedicated namespace and strict read-only enforcement, which prevents data conflicts between GitHub’s UI and your internal source of truth. This turns repository filtering and ruleset targeting into dynamic, business-aware operations rather than static code-level checks.

Claude Code v2.1.284 adds Sonnet 5.5

Anthropic quietly upgrades its local coding agent with Sonnet 5.5 as the new default, bringing a massive 1M context window to developers' terminals. This isn't just a model swap; it fundamentally changes how much codebase history you can keep in memory without manual chunking. The release also patches critical stability issues like malformed image crashes and broken MCP reconnections, making the tool significantly more reliable for complex workflows. For builders, this means deeper context awareness and fewer interruptions during long coding sessions.

Claude Code v2.1.285 patches security and stability

This release prioritizes security hygiene and session reliability over new features. The addition of CLAUDE_CODE_DISABLE_WEB_FETCH is a critical control for enterprise environments needing to restrict external data access. Bug fixes address subtle race conditions in cloud sessions and artifact publishing that could lead to data loss or incorrect state. SSH and plugin installation issues are resolved, ensuring smoother remote workflows. It’s a maintenance update that tightens the tool's operational boundaries.

GPT-6.1 Sol arrives in GitHub Copilot

OpenAI’s GPT-6.1 Sol is now live in GitHub Copilot, targeting the sweet spot between raw power and cost efficiency. Early testing shows it completes multi-step coding tasks with significantly fewer tokens and steps than previous GPT-6 or GPT-5.6 models. This isn't just a version bump; it’s a direct response to developer fatigue over token burn rates during complex agentic workflows. Available across all major IDEs and the Copilot CLI, it shifts the baseline for what constitutes an efficient coding agent. The real win here is the reduction in friction for long-running terminal tasks.

Claude Sonnet 5.5 arrives in GitHub Copilot

Anthropic’s latest model is now live inside GitHub Copilot, shifting the default coding assistant landscape. The key differentiator isn't just raw capability but efficiency: early testing shows it matches Sonnet 5 on coding tasks while using significantly fewer steps and tokens. This translates to noticeably faster task completion for developers working on well-scoped features or bug fixes. Availability spans major IDEs like VS Code, JetBrains, and Xcode, with gradual rollout ensuring broad access across Pro, Business, and Enterprise tiers.

llama.cpp fixes MoE dispatch inefficiency on Vulkan

This release targets a specific but costly bottleneck in Mixture-of-Experts inference on GPUs. The previous tile selection logic wasted significant compute time by misjudging the active workload per expert during dispatch. By correcting how matmul tiles are assigned, the patch ensures workers stay busy instead of idling. This is a quiet optimization that directly improves throughput for large MoE models running on Vulkan backends.
